Pope Paul IV: "Remembering also that, where danger is greater, it must more fully and more diligently be counteracted, We have been concerned lest false prophets or others, even if they have only secular jurisdiction, should wretchedly ensnare the souls of the simple, and drag with them into perdition, destruction and damnation countless peoples committed to their care and rule, either in spiritual or in temporal matters; and We have been concerned also lest it may befall Us to see the abomination of desolation, which was spoken of by the prophet Daniel, in the holy place."
Both true Popes knew exactly of what they spoke - and both spoke of the same: the antichrist.
You still have not proved examples of notorious heresy on the part of Bl. John XXIII, Paul VI, John Paul I and John Paul II. You never will be able to. And if Paul VI was the true Pope of Elder Rome, then the promulgation of the 1970 Missal as universal disciplinary legislation was protected by his infallibility and cannot be an incitement to impiety, as was defined by the holy and oecumenical Synod of Trent.
Do you accept these infallible statements of the First Vatican Council?
1. That which our lord Jesus Christ, the prince of shepherds and great shepherd of the sheep, established in the blessed apostle Peter, for the continual salvation and permanent benefit of the Church, must of necessity remain for ever, by Christ's authority, in the Church which, founded as it is upon a rock, will stand firm until the end of time [45].
5. Therefore, if anyone says that it is not by the institution of Christ the lord himself (that is to say, by divine law) that blessed Peter should have perpetual successors in the primacy over the whole Church; or that the Roman Pontiff is not the successor of blessed Peter in this primacy: let him be anathema. (Pastor Aeternus Ch. 2)
